Although everyone, according to his outlook on life, turns things from bad to good and from good to bad, everyone has his own grade of evolution and reasons accordingly. Sometimes one thing is subtler than others and then it is difficult to judge. There was a time when Wagner's music was not understood, and another time when he was considered the greatest of musicians. Sometimes things are good, but our own evolution makes them less good for us. What we considered good a few years ago may not seem good at a later degree of evolution. At one time a child appreciates a doll most, later it will prefer the work of great sculptors. This proves that at every step and degree of evolution man's idea of good and bad changes. Therefore a thinker will understand that there is no such thing as right or wrong. If there is wrong, all is wrong; if there is right, all is right.
